Patent GB-2105501-A (GB)
Title: Display arrangements
Inventor: THROWER KEITH REX
IPC: H03J1/04
Filed: 1981-09-04
Abstract: A display arrangement for displaying and controlling the operating parameter of a frequency synthesizer for example, comprises a disc 30 which is manually rotatable to set the frequency. The disc carries slits 36 which rotate through the light path between a light source and a photoelectric transducer 38 and the consequent pulses control the frequency of the synthesizer. In addition, however, they activate liquid crystal display units 32A....32M so that the particular LCD unit (32E) in the centre of a display window 22 shows the instantaneous frequency of the synthesizer. As each LCD unit 32 comes into position in the window 22, its displayed value is automatically set to the correct value. In this way, the disc may generate the effect of an infinitely long scale. The values displayed by the LCD units are not changed while they are visible in the window 22. <IMAGE>

Title: Substrate for hybrid and printed circuits
Inventor: RANSOM CHRISTOPHER JOHN
IPC: H01L25/16
Filed: 1981-11-04
Abstract: A hybrid or printed circuit is formed on a substrate (1) which comprises an iron-chromium- aluminium alloy which may also contain Yttrium and which forms a stable inert strongly adhering ceramic layer (5, 6) on its exposed surfaces when heated in an oxidising atmosphere. To produce a hybrid circuit a dielectric paste is printed on the ceramic surface (5) of the alloy to form a platform (9). Conductors (10, 11) are then printed on the dielectric platform (9) and fired. One or more component(s) (8) is/are then soldered to the conductors. <IMAGE>

Title: Games Racket Frame
IPC: A63B49/02
Filed: 1981-11-19
Abstract: A frame for a games racket comprises a hollow plastics moulding (10) which is at least partially reinforced by means of a rigid member integrally moulded therewith. The rigid member can consist of a metal plate (20) having perforations (21) which, when the plate and the plastics material are moulded together, are penetrated by the plastics material, which sets therein to lock the plate to the moulding (10). The plate (20) may, for example, extend over an area corresponding to the crown portion of the frame so as to provide the localised reinforcement, particularly, in the event of impact (e.g. when the racket is dropped on to a hard surface). <IMAGE>

Title: A nozzle with directional outlet jet of continuously changing direction
IPC: B05B1/34
Filed: 1981-12-17
Abstract: A nozzle discharging a stream of continuously changing direction, particularly for use in hydrotherapy to discharge a turbulent jet of an intimate water-air admixture, produces a (preferably adjustable) discharge pattern covering a conical or annular surface of revolution, or variations thereof. The nozzle comprises a body (12), a rotor chamber (50) coaxially within the body, and a rotor body (80) within the chamber. Water is fed to inlet (16) and enters the chamber (50) through tangential inlets (54) to pass through the bore (81) of the rotor body, causing it to rotate, and discharged through a flared mouth (25). A control knob (100) can be rotated to influence the fluid flows and the motion of the rotor body by moving aperture (53) away from plug (112) so that the water enters the chamber (50) axially. Air may be introduced, downstream of the rotor body (80), through inlet (28). <IMAGE>

Title: Macroporous polymer adsorbents
IPC: B01J20/26
Filed: 1982-01-27
Abstract: The invention provides an absorption method for separating gases or liquids from gas or liquid mixtures using as the absorbant a macroporous polymer produced from a cross-linked aromatic homo or copolymer whose polarity optionally may have been varied by means of an electrophilic aromatic substitution, addition, eliminating, and/or reducing reactions. The polymer is in particulate form with a surface area greater than 50 m<2>/g. Macroporous polymers are produced by copolymerizing a 60/40 divinyl benzene/ethyl benzene mixture, followed by sulphonation, acylation, alkylation, nitration (optionally followed by reduction), bromination, nitration/bromination (optionally followed by Br replacement with CN), or by introduction of aminoacid residues.

Patent GB-2105616-A (GB)
Title: Charging apparatus for an electrostatic gun
Inventor: LEVER ROBERT CHARLES
IPC: B05B5/16
Filed: 1982-09-07
Abstract: The apparatus, which is for use in charging powder particles to be sprayed by gun onto an article in a powder coating process, incorporates a charging chamber (3) for charging the powder particles, having a needle point discharge electrode (10) and one or more attractor electrodes (7, 8) held at a differing potential than the discharge electrode. To prevent build-up of charged powder particles on the attractor electrodes (7, 8) they are made air-permeable and during operation air is continuously fed thereto through air ducts (9) connected to housings (7', 8') around the attractor electrodes. This results in improved uniformity of charging of the particles passing through the charging chamber. <IMAGE>

Means may be provided for incorporating fertilizer or other chemical supply to the soil in which the implement is used. The principal use of the implement is in providing ridges for root crops without considerable penetration of the discs and thereby reducing damage to the crops. <IMAGE>
Patent GB-2150675-A (GB)
Title: Heat exchanger
Inventor: CAIRNS SYDNEY
IPC: F24B1/183
Filed: 1984-10-29
Abstract: A domestic back boiler has water-filled side walls (11, 12) from which are cantilevered water-filled heat-exchange elements (17-20) arranged in left hand and right hand member pairs so as closely to resemble the conventional back boilers. A cover plate (23) increased visual appeal and hides gaps (21,22) between the distal end of the cantilevered elements. By cantilevering the elements and providing the gaps (21,22). cleaning of the surfaces of the flueways (28 and 31) is much easier than in the conventional boilers but another important advantage is that in manufacture of the boilers the width dimension of the heat-exchange elements has no longer to be so closely controlled as with the conventional boilers, in the construction of which each of these elements has to be welded watertight at opposite ends thereof to the two side walls (11, 12). <IMAGE>

Title: Explosive device and method of use therefor
Inventor: CASEY KENNETH
IPC: F42B3/00
Filed: 1984-11-23
Abstract: An explosive device is described, particularly suitable for such purposes as cutting thick cables, breaking blocks, seismic operations, etc. For cutting cables 51, Fig. 5, a plastic device 52 may be used with snap-fit jaws 53 on the end of a holder 54 formed with a coaxial plug 58. In this, as in other forms of the invention, the explosive 50 (here shown in the form of tubular explosive elements 59a,59b) surrounds a cavity 57, which is symmetrical about an axis, and the mouth of which has a cross-sectional area about the same or greater than the area of any other cross-section perpendicular to the axis. The mouth of the cavity 57 is surrounded by explosive 50, the thickness of the explosive surrounding the mouth being greater than the critical diameter of the explosive. In the embodiment shown for use in cutting a cable a blasting cap 55 is inserted into a capwell formed in the explosive element 59b. In other embodiments (Figs. 2,9,10,10A not shown) the device is formed from an integral mass of explosive. In a device for rock blasting, Fig. 7, a cavity shaping device 60 is placed upon a boulder 61 and a sausage- shaped package of explosive 62 is cut into two portions to expose a face of explosive which is slapped over the cavity shaping device and onto the boulder. <IMAGE>
